The Navy won't investigate Kerry, so I don't think the AF would spend their time on Mr. Rather either.
I think you are correct, HOWEVER this is the TEXAS Air National Guard. Perhaps if we spoke with Governor Rick Perry (R) he might have someone look into it.
As a matter of fact a friend of mine and former city councilman retired 4 or 5 years ago as the top enlisted man in the Texas Air National Guard. I think I shall give him a call.
